The difference between Oxalis grandiflora and Oxalis

1. Difference of blades

The large-flowered Oxalis has basal leaves with thin and weak petioles, about 7-10 cm long, with joints at the base, and the leaflets are obovate or broadly obovate, about 1.5-2 cm long and 2.5-3 cm wide, with an obtuse tip and a broad cuneate base. The surface is smooth and hairless, and the back is sparsely pubescent.

Oxalis is divided into basal leaves and stem leaves, which are alternate on the stems. The leaflets are inverted heart-shaped, smaller than the former, about 4-16 mm long, 4-22 mm wide, and have soft hairs on both sides.

2. The difference between flowers

The large-flowered Oxalis has an umbel inflorescence, which is basal or nearly basal, obviously longer than the leaves, and the petals are purple-red and broadly obovate.

Oxalis flowers are solitary or several flowers are gathered in umbels, axillary, and the same length as the leaves. The petals are yellow in color and oblong in shape.
